Mars Ice Access Mission is a key robotic precursor mission to future human exploration planning. It is part of ESA’s Exploration Programme, named “Terrae Novae”, encompassing all ESA’s human and robotic activities related to the exploration and utilisation of Earth Orbit, Moon and Mars. The “Mars Ice Access Mission Study” is a Pre-Phase A level study. The objective of the study was to propose a preliminary design of a mission aiming to:

Passive intermodulation is a real threat to all types of payloads. In some cases, it could even lead to total lost of the spaceship. Despite of this, there is very weak understanding of the parameters that generate this unwanted interference as well as their influence in the amplitude of the interfering signal. In addition, there is a total lack of agreed testing techniques, procedures and methodologies as well as justified test margins, as has already been recently stated by the European community (National Delegations, satellite operators and Eurospace).

Classical control design techniques used for flexible spacecraft are based on single axis design approaches to control the rigid-body motion complemented by low-pass and notch filters to suppress the resonant peaks of the low-frequency flexible modes. These techniques are inherently relying on a priori knowledge of the structural flexible modes and introduce significant conservatism in the control and structural design, dictated by the need to separate the controller bandwidth from the flexible modes frequency.

While AI technologies have shown promise in various applications in the space industry, their adoption within spacecraft flight software has yet to happen in a significant manner. This is due to a number of factors, including the relatively low computing power available onboard traditional spacecraft, the long development process required in the industry and the lack of opportunities for in-orbit demonstrations. In ESA's OPS-SAT satellite, Airbus teams identified a unique opportunity to quickly test promising algorithms in orbit as the industry seeks to resolve the issues listed above.

A previous study (TRP Star sensing based safe mode) confirmed the interest of using star tracker as primary sensor in a generic safe mode: versatility, suitability to complex requirements and constraints (e.g.

Following on from the successful Venus Express mission (2006 – 2014), the EnVision mission is a mission to observe the surface of Venus at an unprecedented resolution, investigating signs of active geology and looking for evidence of the past existence of oceans. EnVision is meant to help in the understanding of why this most Earth-like planet has turned out so differently and open a new era in the exploration of our closest neighbour. EnVision is proposed as a joint mission with NASA, with payload elements funded by the ESA Member States.

The Mars Surface Platform Capabilities Study aimed to provide ESA with an assessment of the state of the art in Mars lander technologies using ESA/European technologies with flight heritage. Airbus’ Mars lander experience is taken from the Beagle 2 probe launched in 2003 on board Mars Express.
The objectives of the study were to:

There is increased attention being given to safeguarding Earth's orbital environment, as reflected by the number of relevant regulations that are being set forward by national governments and international organisations. Among others, ESA has published a Space Debris Mitigation Policy for Agency Projects (ESA/ADMIN/IPOL(2014)2), supported by the corresponding ESA Space Debris Mitigation Compliance Verification Guidelines (ESSB-HB-U-002).
